Quantum-like modeling: cognition, decision making,and rationality

摘要

Recent years were characterized by the real explosion of interest to applications of quantum measurement theory and other parts of quantum formalism outside of physics, especially in psychology, decision making, economics, finances, and social science (as well as in genetics and molecular biology), see, e.g., monographs (Khrennikov 2004, 2010; Busemeyer and Bruza 2012; Haven 2013; Asano et al. 2015; Bagarello 2019; Schade 2019). Quantum-like models reflect those specialties of cognitive information processing which match well with the quantum formalism. We emphasize that the strategy of quantum-like modeling does not assume that the whole body of quantum theory should be explored. The quantum-like representation of mental states and (self-)observations is operational. It does not provide the complete picture of cognitive processes including functioning of neuronal networks in the brain. In principle, one can search for finer models, so to say prequantum models, and couple such models with the quantum operational description.
